MARVEN KELLEY, OF LULING, TEXAS.

SIGNALING-BOILER.

Application filed october 25, 191s.

To all fr0/wm t may concern:

Be it known that I, MARVEN KELLEY, a citizen of the United States,residing at Luling, in the county of Caldwell and State of Texas, haveinvented new and usetul Improvements in Signaling-Boilers, of which thefollowing is a speciiication.

This invention comprehends generally improvements in domestic cookingvessels, and more particularly has reference to a signaling boiler.

This invention has for its primary object to provide a device of theabove mentioned character wherein combined testing and outlet closingmeans is employed and is normally disposed in a set position above apotato or other vegetable which is being cooked, while acting inconjunction therewith is improved resilient means for normally exertinga pressure on the testing means so that the testing means will penetratethe vegetable when the latter has become sufficiently cooked and at thetime the testing means moves downwardly, the steam outlets will beclosed so that the steam within the body will be directed through thesignaling means, such as a whistle in the top or lid on the body, thusindicating the fact that the vegetables within the boiler are properlycooked.

It is a more specific object of this invention to construct the body ofthe boiler in a novel form so that potatoes or other vegetables may beproperly supported therein, to also provide a combined tester and steamoutlet closure of novel configuration and to also provide a lid of theimproved construction for removably closing the body "for operablysupporting the testing and closing means.

Among the other aims and object-s oi this invention may be recited theprovision oi a device of the character described with a view tocompactness, and in which the number of. parts are few, the constructionsimple and the cost of production low and the efliciency high.

Other improvements and novel details in the construction and arrangementof the various parts of the apparatus will be brought out more in detailin the description to follow, which for a -clear understanding of theinvention shouldbe considered in connection with-the accompanyingdrawings torming a part hereof, and wherein is disclosed for the purposeof illustration Specification of Letters Patent.

Patented May 4, 1920.

Serial No. 259,687'` a convenient and satisfactory embodiment of theinvention. It is to be noted in this connection that minor changes inthe construction andl arrangement of parts may be made without departingfrom the principle of operation of the various parts.

The invention is clearly illustrated in the accompanying drawings, -inwhich :M-

Figure l is a vertical sectional view ot the device showing theparts'arranged in a set position.

Fig. 2 is a similar view showing the parts arranged in a signalingposition.

Fig. 3 is a perspective detail of the combined tester outlet closure.

Fig. 4 is a top plan view of the body with the lid removed.

Similar characters of reference are employed in all of the abovedescribed views, to indicate corresponding parts.

Referring now, more'particularly to the accompanying drawings there isprovided a cylindrical body l having a transverse partition 2 thereinwhich divides the body into a water chamber or compartment 3 and a steamcompartment 4, the partition being provided with perforations 5 topermit of the passage of steam into the compartment l while prongs 6rise upwardly from the partition and serve .as means for supportingsuitable vegetables, such as potatoes 7. The partition is formed with anopening 8 about which is formed an upright eXteriorly threaded collar 9for accommodating a winged cap l0 which serves as a means tor removablyclosing the opening which in turn permits of the filling of the chamberor compartment 3 with water. A tube 1l has one end mounted in thepartition to communicate with the compartment 3 while the opposite endis mounted through the body'l as indicated in the drawings and this tubepermits of steam to pass from the chamber or compartment 4; to a pointremote from the body, as is apparent.

A hooded lid or cover 12 is now employed and is formed at its lower edgewith a depending ear designed for removable engagement with a hook, thehanger 13 projecting from the upper edge of the body and thisarrangement serves as a means for removably connecting the cover to thebody while the lower flanged edge 14 of the cover rests on the upperianged edge 15 of the body to provide an effective engagement betweenthe cover and the body. A whistle 16 is mounted in the hood portion ofthe cover 12 for a purpose that will presently appear, likewise the topof the cover is prowithin the steam compartment t and for closing theopening 17 and the outlet tube 11 to assure of steam passing through thewhistle 16 for sounding the latter at the time the potatoes are properlycooked, a tester rod 18 is employed and is slidably disposed through theopening 17 in the cover, the lower end thereof being pointed as at 19and designed to normally rest on the upper edge of the adjacentpotato 7.An offset arm 20 is formed with an attaching sleeve 21 which is securedto the rod 18 near the pointed end thereof in such a manner that theouter portion of the arm 2O will be disposed over the upper end of thetube 11 so that when the potato becomes properly cooked it will bepenetrated by the pointed end of the rod during the downward movement ofthe rod, and at the same time the outer portion of the arm will closethe upper end of the tube 11. Simultaneously with the closing of thetube 11 the handle knob 22 carried on the upper projecting end of therod will set against the opening 17 to permit the passage of steamthrough this opening and as steam is prevented from passing through theoutlet tube Y 11 the only passage of escape is through the whistle 16and of course when the steam passes through this whistle the latter willbe sounded to indicate that the vegetables are properly cooked.

Cooperating with the`rod 18 for insuring of an effective operationthereof are improved spring members 23 the securingk portions of whichare connected by suitable fasteners 24C to opposite points of the hood'-ed portion of the cover 12, while the outer and upturned engagingportions 25 are positioned in close relation with each other so as toengage against opposite sides of the rod, while the tension of thespring members 23 `is such4 that a downward pressure is at all timesexerted on the rod 18 so as to assure of the penetration of thev nearestpotato 7 when the latter has become sufficiently or properly cooked, asis apparent.

It is believed in view of the-'foregoinggdescription that a furtherdetailed description of the operation of the invention is entirelyunnecessary. Likewise it is believed that the advantages of theinvention will be readily ap arent. Y

s many changesv could be made 'in the above construction and manyapparently widely different embodiments of this invention cou-ld beAmade without departing from the scope thereof it is intended that allmatter contained in the above description or shown in the accompanyingdrawings shall be interpreted as illustrative and not in a limitedsense. It is also to be understood that the language used'in thefollowing claims is intended to cover all the generic and specificfeatures of the invention herein described and all statements of thescope of the invention which as a matter of language might be said tofall therebetween.

What is claimed is 1. A signaling boiler having a water and a steamcompartment and a steam outlet, vegetable supporting means,` a whistle,a combined testing means and steam outlet closure means adapted fordisposition on the nearest vegetable carried on the vegetable supportingmeans, and resilient means coperating with the last mentioned means andexerting a downward pressure. thereon, whereby when the said vegetablehas properly cooked, the said testing means may cnter the same to effectthe operation of the outlet closing means, thereby directing the steamthrough the whistle.

2. A signaling boiler having a Water compartment and a steam compartmentand a steam outlet for the steam compartment, a cover on the boiler andprovided with a central opening therein, a whistle mounted in the cover,a rod passing slidably through the opening in the cover and having' itslower end pointed, vegetable supporting means, the lower end of the rod'being adapt'- ed for positioning on a vegetable on said means, an armcarried by and offset from the rod and positioned adjacent the steamoutlet, and spring members mounted on the cover and exerting a downwardpressure on the rod so that when the vegetable with which the vegetabletester engages is cooked the latter will penetrate .theV same and thusbring the offset arm over the steam outlet, thereby directing the steamthrough the whistle, as herein shown and specified'.

3. A signaling boiler havinga partition therein, vegetable supportingmeans carried above the partition, a cover for the boiler, a Whistle, asteam outlet, and a combined vegetable tester andv outlet closuremedium` engageable witha vegetable upon the vegetable supporting means,whereby when said vegetable becomes cooked, the steam outlet may beclosed and steam directed through the whistle as herein shownandfspecified.

VIn testimony whereof I affix mysi nature. Y
